Nantucket Airlines operates island shuttle services in close partnership with Cape Air, connecting travelers between Nantucket, Martha's Vineyard, Cape Cod, and regional hubs like Boston Logan. Because these flights utilize small feeder aircraft such as the 9-passenger Cessna 402 and the 11-passenger Tecnam P2012 Traveller, traditional airline baggage expectations do not apply.
Passengers flying on Nantucket Airlines do not have access to overhead bins in the passenger cabin. Instead, the carrier relies on a plane-side valet bag system and strict weight-and-balance protocols to manage passenger luggage safely.
Nantucket Airlines (operated alongside Cape Air) allows passengers one small personal item under the seat and one checked bag, subject to route fare rules and fees. Due to small aircraft cabin sizes (Cessna 402 and Tecnam P2012), overhead bins are unavailable. Standard carry-on luggage must be valet-checked at the aircraft steps before flight and retrieved plane-side upon arrival.
Baggage Allowance Snapshot
Nantucket Airlines operates small feeder aircraft without overhead bins, requiring carry-on bags to be valet-checked at plane-side. Personal items must fit entirely beneath the seat, and checked luggage is subject to route fees and strict aircraft weight limits.
What can change: Exact checked bag fees vary based on booking class, point-to-point vs. interline itineraries, and operator dispatch weight restrictions.

Baggage rules can vary by fare, cabin, route, operating carrier, traveler status, and purchase channel. BaggageBase separates published rules from practical guidance.
How BaggageBase Checks This Information
BaggageBase reviews passenger contracts of carriage, regional flight dispatch manuals, Federal Aviation Administration (FAA) regional aircraft specifications, and official ticketing terms from Cape Air and Nantucket Airlines.
When Nantucket Airlines routes fall under broader partner ticketing agreements, BaggageBase verifies tariff schedules directly against active feeder flight operations. Specific baggage fees can vary depending on ticket class and connection partners, so exact costs should be double-checked against your booking itinerary prior to departure.
Nantucket Airlines Fleet Context: Why Baggage Rules Differ
Flying on Nantucket Airlines differs significantly from flying on a commercial jetliner. The fleet consists primarily of small twin-engine aircraft designed for short regional hops. These aircraft lack the interior cabin volume necessary to install overhead storage bins.
Because of this physical design, every piece of luggage except for a tiny personal item must be loaded into external wing lockers, nose bays, or aft cargo holds.
Plane-Side Valet Bag Service
To give passengers quick access to their luggage, Nantucket Airlines uses a Plane-Side Valet Bag Service. You carry your small duffel or rollaboard bag across the tarmac to the aircraft steps. Ground crew or the flight pilot tags the bag and stows it in an exterior compartment. Upon arrival at your destination island or airfield, crew members unload valet bags onto the tarmac so you can collect them immediately upon stepping off the aircraft.
Aircraft Weight and Balance Limits
Small aircraft are subject to strict FAA weight-and-balance regulations. The combined weight of passengers, fuel, and cargo must remain within precise thresholds before the flight is cleared for takeoff. On flights with full passenger loads or heavy weather fuel requirements, ground dispatchers may classify certain extra or heavy bags as space-available cargo. In these instances, your luggage may be routed on the next available flight to the island.
Nantucket Airlines Personal Item Size and Under-Seat Allowance
Passengers on Nantucket Airlines may bring one small personal item into the aircraft cabin free of charge. However, because space beneath regional aircraft seats is restricted by structural metal framing, personal items must remain small.
- Maximum Dimensions: 14.5 x 12 x 4.5 inches (37 x 30 x 11 cm)
- Maximum Weight: Must be light enough to comfortably manage without impeding aircraft movement.
- Storage Location: Strictly beneath the seat directly in front of you.
Review our detailed guide on what counts as a personal item to select a bag that fits these smaller constraints.
Small purses, slim laptop sleeves, or compact cross-body pouches fit easily under the seat. Standard travel backpacks or rigid totes will not fit beneath Cessna or Tecnam seats and must be handled as plane-side valet bags or checked luggage.
Nantucket Airlines Carry-On Policy and Plane-Side Valet Service
Nantucket Airlines does not allow traditional carry-on luggage inside the passenger cabin due to the complete absence of overhead bins. Instead, bags that would normally qualify as carry-ons on larger jets are processed as valet carry-ons.
- Maximum Dimensions: Up to 45 linear inches / 114 cm (Length + Width + Height).
- Maximum Weight: 30 lbs / 13.6 kg.
- Handling Method: Handed directly to ground staff at the aircraft stairs and returned plane-side immediately after landing.
Understanding carry-on vs. personal item guidelines helps avoid boarding delays. When arriving at the airport gate, inform the service agent if you have a valet bag so they can attach the correct plane-side baggage tag before you walk onto the ramp.
Nantucket Airlines Checked Bag Fees and Size Limits
Checked luggage on Nantucket Airlines is stowed in the aircraft’s main baggage holds. Standard dimension and weight limits align with broader aviation standards, but fees depend on your route and ticketing arrangement.
- Maximum Linear Dimensions: 62 linear inches / 157 cm (L + W + H)
- Maximum Standard Weight: 50 lbs / 23 kg per bag
Read our breakdown of checked bag vs. carry-on trade-offs to decide whether checking luggage or using valet service makes sense for your trip.
| Checked Bag Category | Maximum Dimensions | Maximum Weight | Typical Fee Scope | Key Condition |
|---|---|---|---|---|
| First Checked Bag | 62 linear in / 157 cm | 50 lbs / 23 kg | Standard Route Fee | Fee varies by fare class & connection |
| Second Checked Bag | 62 linear in / 157 cm | 50 lbs / 23 kg | Additional Route Fee | Transported on space-available basis |
| 3rd + Additional Bags | 62 linear in / 157 cm | 50 lbs / 23 kg | Excess Fee Tier | Subject to strict aircraft payload limits |
Fees are collected during check-in at the airport or when purchasing tickets online. Because regional flights operate with restricted overall cargo space, third or fourth bags are held on standby status if payload limits are reached.
Nantucket Airlines Overweight and Oversized Baggage Fees
Bags that exceed standard weight or dimensional thresholds require extra handling and consume significant aircraft weight capacity. Nantucket Airlines enforces clear limits on heavy and bulky luggage.
Overweight Surcharges
- 51 to 70 lbs (23–32 kg): Subject to standard overweight fee tiers; accepted if total aircraft weight permits.
- 71 to 100 lbs (32–45 kg): Subject to heavy overweight surcharges; handled strictly on a space-available basis.
- Over 100 lbs (45 kg): Strictly prohibited. Bags over 100 lbs will not be accepted for transport on regional feeder aircraft under any circumstances.
Oversized Surcharges
- 63 to 80 linear inches (158–203 cm): Subject to oversized bag fees.
- Over 80 linear inches (203 cm): Strictly prohibited. Large items exceeding 80 linear inches cannot physically fit through cargo bay doors on Cessna 402 or Tecnam P2012 aircraft.
| Condition | Weight / Size Threshold | Applied Fee / Status | Acceptance Limit |
|---|---|---|---|
| Standard Allowance | Up to 50 lbs / 62 linear in | Included or Standard Fee | Guaranteed space if booked early |
| Overweight Tier 1 | 51 lbs – 70 lbs | Overweight Surcharge | Accepted subject to weight limits |
| Overweight Tier 2 | 71 lbs – 100 lbs | Heavy Weight Surcharge | Standby / Space-available basis |
| Oversized | 63 in – 80 linear in | Oversize Surcharge | Must fit physical cargo door dimensions |
| Absolute Maximum | > 100 lbs or > 80 linear in | Not Accepted | Prohibited on feeder fleet |
How Ticket Fares and Connecting Flights Impact Baggage Rules
Many passengers fly Nantucket Airlines as part of a longer journey connecting through major hubs like Boston Logan (BOS). Understanding how joint tickets operate is critical for avoiding surprise fees at airport transfers.
Point-to-Point Island Fares
If you purchase a direct ticket between Nantucket and Hyannis, New Bedford, or Boston on Nantucket Airlines/Cape Air stock, standard regional feeder baggage fees and allowances apply directly.
Interline and Codeshare Tickets
Nantucket Airlines and Cape Air maintain interline and codeshare partnerships with major trunk carriers including JetBlue, United Airlines, American Airlines, and Delta Air Lines.
- Checked Bag Allowance: If your entire itinerary is booked on a single joint ticket (for example, flying United Airlines from Chicago to Boston, connecting to Nantucket Airlines), the checked baggage allowance and fee rules of the marketing carrier may apply to your checked luggage.
- Physical Cabin Limitations: Regardless of your connecting airline or cabin ticket class (even First or Business Class), the physical cabin rules of the regional feeder flight remain non-negotiable. Standard carry-on rollaboards cannot go into the cabin on Cessna or Tecnam aircraft and must be valet-checked at the ramp.
Military Waivers and Partner Status Benefits
Nantucket Airlines provides fee waivers for qualified military personnel, though airline status benefits vary by ticket arrangement.
- Active Duty U.S. Military: Active duty members of the U.S. Armed Forces traveling on official orders or personal leave receive fee waivers for up to two standard checked bags. Valid active duty military identification must be presented at check-in.
- Partner Loyalty Programs: Frequent flyer status with partner airlines (such as JetBlue Mosaic or United Premier) may provide checked bag fee waivers when the ticket is issued on partner ticket stock. However, status benefits do not override physical aircraft dimensions or maximum cargo weight caps. Check the airline's baggage tool or official policy before payment or departure.
Traveling with Special Gear, Children, and Pets on Nantucket Flights
Traveling to an island destination often involves gear, strollers, or household pets. Nantucket Airlines accommodates special luggage under regional safety rules.
Children and Infants
- Strollers and Car Seats: Fully collapsible strollers and infant car seats are checked free of charge. You can check these items at the ticket counter or leave them plane-side during boarding for retrieval upon landing.
- Diaper Bags: One standard diaper bag is permitted in addition to personal items for passengers traveling with infants.
Mobility and Medical Devices
- Wheelchairs and Assistive Gear: Wheelchairs, walkers, crutches, and CPAP machines travel free of charge. Manual wheelchairs are stowed in the aircraft cargo hold.
- Battery Rules: Spillable and non-spillable batteries used in mobility equipment must meet FAA hazardous material safety checks prior to loading.
Golf Bags and Sports Gear
- Golf Equipment: Golf bags are accepted as standard checked items if they weigh 50 lbs or less. Due to space limits, large hard-shell golf travel cases are accepted on a space-available basis.
- Surfboards and Fishing Gear: Surfboards, paddleboards, and long fishing rod cases are restricted by cargo door dimensions. Items exceeding 80 inches in length generally cannot be accommodated on feeder aircraft.
Pet Policy
- In-Cabin Pets: Small dogs and cats are permitted in the cabin for a fee, provided they remain inside an approved soft-sided carrier that fits under the seat ahead. Advanced reservations are required as total pets per flight are strictly limited.
Plane-Side Rejections and Standby Luggage Handling
If a bag exceeds size limits or if an aircraft reaches its maximum operational takeoff weight, ground agents must reject the item for immediate flight dispatch.
Standby and Deferred Luggage Procedures
When luggage is classified as "space-available," ground operations handle the item through a structured process:
- Tagging and Hold: The bag is tagged with a priority standby sticker at the airfield counter.
- Next Available Flight: Ground operations load the deferred item onto the next scheduled departure to Nantucket or Cape Cod with available payload capacity.
- Island Terminal Collection: Passengers pick up delayed baggage at the destination airport terminal office or arrange local delivery where applicable.
To minimize the risk of separated luggage, ensure all checked items remain strictly under 50 lbs (23 kg).
Before You Fly Checklist for Nantucket Airlines
Follow these essential steps before heading to the airfield to avoid baggage delays or fees.
- Measure your personal item. Ensure your purse, laptop sleeve, or small pouch is within 14.5 x 12 x 4.5 inches to guarantee under-seat fit on regional aircraft.
- Pack medicine and valuables separately. Never place keys, medication, passports, or critical electronics into valet or checked bags, as valet bags are loaded into exterior aircraft compartments.
- Verify carry-on valet weight. Keep your plane-side valet luggage at or under 30 lbs (13.6 kg) and 45 linear inches so it can be accepted at the aircraft stairs.
- Weigh checked bags before airport arrival. Keep checked bags under 50 lbs (23 kg) to prevent heavy bag surcharges and standby delays on high-demand flights.
- Arrive early with special items. Give ticket agents extra time to inspect and tag golf bags, strollers, or bulky island gear before flight dispatch.
- Prepare for space-available delays. Carry essential overnight garments in your under-seat personal item in case heavy cargo travels on a subsequent flight due to FAA weight limitations.
Frequently Asked Questions
Does Nantucket Airlines allow standard 22-inch carry-on bags in the cabin?
No. Standard 22-inch carry-on bags cannot fit inside the cabin because Cessna 402 and Tecnam P2012 regional aircraft do not have overhead bins. Standard carry-on luggage must be tagged and handed to flight staff at the airstairs as plane-side valet baggage.
Where do I drop off and pick up my valet carry-on bag?
You drop off your valet carry-on bag directly at the airstairs of the plane prior to climbing aboard. Upon landing, airport staff unload valet bags onto the tarmac so you can pick up your luggage immediately as you deplane.
What is the exact personal item size limit for Nantucket Airlines flights?
The maximum personal item dimensions are 14.5 x 12 x 4.5 inches (37 x 30 x 11 cm). Personal items must fit entirely beneath the seat in front of you without blocking aisles or seat frames.
How much does a checked bag cost on Nantucket Airlines?
Checked bag fees vary depending on whether you purchase a point-to-point regional fare or connect on an interline ticket with a partner airline. Exact fee schedules can be checked through the Cape Air/Nantucket Airlines booking portal during check-in.
Can my luggage be delayed due to aircraft weight limits?
Yes, luggage can be delayed if the flight reaches maximum FAA payload limits. Excess, overweight, or secondary checked bags may be marked as space-available cargo and transported on the next scheduled flight.
Can I bring golf clubs on flights to Nantucket?
Yes, golf bags are accepted as checked baggage provided they weigh 50 lbs (23 kg) or less. Hard travel cases or oversized bags are subject to space-available constraints in the aircraft hold.
Are strollers checked for free on Nantucket Airlines?
Yes, strollers and infant car seats are checked free of charge for passengers traveling with young children. You can leave strollers plane-side at the aircraft stairs and retrieve them upon landing.
Summary and Final Checklist
When traveling with Nantucket Airlines, remember that regional feeder aircraft operate under strict space and weight rules. Traditional overhead storage bins do not exist on these flights. Plan to bring a small under-seat personal item (under 14.5 x 12 x 4.5 inches) for critical personal essentials, medicine, and travel documents.
Standard carry-on bags up to 45 linear inches and 30 lbs travel via the plane-side valet system, where you hand them to the flight crew at the aircraft steps and pick them up on the tarmac upon arrival. Checked bags must remain under 50 lbs and 62 linear inches to avoid extra fees or standby delays.
Always confirm whether your reservation is an isolated island hop or a joint interline itinerary. Interline connections may change fee structures, but the physical cabin limits of regional feeder aircraft always apply. Double-check your weight totals before heading to the airfield terminal.
Airline baggage rules and fees can change by route, fare, cabin, operating carrier, traveler status, purchase channel, and departure date. Check the airline's official baggage policy or calculator before booking, paying, or traveling. BaggageBase reviews information for 2026 where possible, but the airline's published terms remain the final authority.
